转盘柱中存留分数的CFD模拟研究
转盘柱中分散相存留分数是影响其设计放大的重要因素。本工作通过计算流体力学（CFD）软件对转盘柱中水煤油两相流水力学性能进行模拟计算。两相逆流操作，水是连续相，煤油为分散相。求得了流场分布和分散相存留分数分布，并研究了两相表观流速以及转盘转速对存留分数的影响，模拟结果与已发表的文献实验数据吻合较好。CFD模拟为减少水力学实验和进一步研究转盘柱水力学性能和传质打下了基础。...

In this paper, the hydrodynamic characteristics of two-phase flow in a RDC were studied by means of computational fluid dynamics （CFD） software. Two phases consisting of the dispersed phase （kerosene） and continuous phase （water） were introduced in countercurrent operation. The distribution of flow filed and the dispersed phase holdup was obtained, in addition, the changes of the dispersed holdup with two-phase superficial velocity and rotation speed were also discussed. The results from simulations and the experiment data of the published literature are in good agreement. The presented CFD predictions will provide a possible way |
